reset ' test out of this skill '
When you have used, in one particular language group (for example FR > ENg), ' three times 'test out of this skill' without success, then you don't have the possibility ' test out of this skill ' for other language groups with the same target language , for example D > Eng. The possibility of three times ' test out of this skill' should be separated for each language group, or it should be enabled to reset for some lingots.
Yes, and even more, please let us "test out" as often as we want, no matter whether the test was failed or not. Make this whole tree more flexible, to allow everyone to follow his or her own personal learning path, instead of enforcing a fixed sequence. Let us choose to jump over lessons and return to them later. I have already made this suggestion elsewhere, but I repeat it here, because I think it would allow for a much more pleasing learning experience.
DL looks only at the language to learn. If you learn English from French, Dutch, Polish,.. it counts only points for English, wathever language you are learning from. Losing the ' three times 'test out of this skill' in one language group for learning English, let you lose the ' three times 'test out of this skill' for all other languages where you are learning from, when the learned language English is. Maybe it is not a bug, DL looks only to th language to be learned and doesn't look to the language you are learning from.
